LOS ANGELES (CNS) - USC researchers have found the likely order in which COVID-19 symptoms first appear: fever, then cough and muscle pain, followed by nausea, and/or vomiting, and diarrhea, it was announced Thursday.Knowing the order of COVID-19's symptoms may help patients seek care promptly or decide sooner than later to self isolate, according to scientists at the USC Michelson Center for Convergent Bioscience. The information also may help doctors rule out other illnesses, or help doctors plan how to treat patients, and perhaps intervene earlier in the disease.The study, which appears in the journal Frontiers in Public Health, was led by doctoral candidate Joseph Larsen and scientists Peter Kuhn and James Hicks at the USC Michelson Center's Convergent Science Institute in Cancer."This order is especially important to know when we have overlapping cycles of illnesses like the flu that coincide with infections of COVID-19," said Kuhn, a USC professor of medicine, biomedical engineering, and aerospace and mechanical engineering. "Doctors can determine what steps to take to care for the patient, and they may prevent the patient's condition from worsening."Fever and cough are frequently associated with a variety of respiratory illnesses, including influenza, Middle East Respiratory Syndrome and Severe Acute Respiratory Syndrome. But the timing and symptoms in the upper and lower gastrointestinal tract set COVID-19 apart."Given that there are now better approaches to treatments for COVID- 19, identifying patients earlier could reduce hospitalization time," Larsen said.To determine COVID symptom chronology, the authors analyzed more than 55,000 confirmed coronavirus cases in China collected from Feb. 16 to Feb. 24 by the World Health Organization. They also studied a dataset of nearly 1,100 cases collected from Dec. 11 through Jan. 29 by the China Medical Treatment Expert Group via the National Health Commission of China.In addition, to compare the order of COVID-19 symptoms to influenza, the researchers examined data from 2,470 cases in North America, Europe and the Southern Hemisphere, which were reported to health authorities from 1994 to 1998."The order of the symptoms matter, " Larsen said. "Knowing that each illness progresses differently means that doctors can identify sooner whether someone likely has COVID-19, or another illness, which can help them make better treatment decisions." 2440

LONDON (AP) — The World Health Organization is acknowledging the possibility that COVID-19 might be spread in the air under certain conditions.This comes after an open letter from more than 200 scientists published this week urging the agency to do so.WHO has long dismissed the possibility that the coronavirus is airborne except for certain risky medical procedures, such as when patients are first put on breathing machines.But it noted on Thursday that studies evaluating COVID-19 outbreaks in restaurants, choir practices and fitness classes suggested the virus might have been spread in the air. 609

LOS ANGELES (AP) — Republican Young Kim has defeated Democratic U.S. Rep. Gil Cisneros in Southern California. The contest was a rematch from 2018, when Cisneros delivered an upset in what had been a longstanding GOP district anchored in Orange County. Kim’s victory Friday in the 39th Congressional District overcame President Donald Trump’s poor performance in heavily Democratic California, where he got only one-third of the votes. The former state lawmaker was born in South Korea and grew up in Guam. Another California Republican born in South Korea — Michelle Steel — defeated Democratic U.S. Rep. Harley Rouda in another Orange County district. 661

LOS ANGELES (AP) — Federal investigators who examined the burned-out wreckage of a scuba diving boat have not been able to determine what ignited a fire that killed 34 people off the California coast, a law enforcement official said Friday.Teams from the FBI and Bureau of Alcohol, Tobacco, Firearms and Explosives left after spending two weeks reviewing what remains of the Conception, according to an official with knowledge of the investigation.Parts of the vessel have been sent to labs for additional testing, said the official, who was not authorized to release the information publicly and spoke on the condition of anonymity. There is no indication anyone intentionally set the Sept. 2 fire.Six crew members were asleep when the fire broke out before dawn and trapped those sleeping in bunks below deck. Coast Guard rules require a roving watchman, and authorities were looking into possible criminal charges that would likely focus on an obscure federal law known as the seaman's manslaughter statute.RELATED: San Diego woman killed in deadly Conception boat fire off Santa BarbaraWith the boat propped up by braces and scaffolding, investigators wearing protective suits walked over planks to inspect and document the burned vessel at Port Hueneme, a naval base more than 60 miles (97 kilometers) northwest of Los Angeles, the official said. Some parts of the boat washed away because it was submerged for two weeks off Santa Cruz Island.Authorities also will examine hundreds of documents seized from the boat's owner, Truth Aquatics Inc., days after the fire.The Coast Guard, FBI and U.S. attorney's office in Los Angeles are leading a criminal investigation into the blaze, and the National Transportation Safety Board is conducting a safety inquiry.The captain and four crew members asleep on the vessel's upper deck survived the fire. The sixth, a 26-year-old deckhand named Allie Kurtz, was sleeping below deck and perished with the boat's 33 passengers.Truth Aquatics preemptively filed a federal lawsuit under a pre-Civil War maritime law that shields boat owners from monetary damages in a disaster at sea.Ryan Sims, a cook on the boat who broke his leg trying to escape the flames, claimed in a separate lawsuit that the boat was unseaworthy and operated in an unsafe manner.Coast Guard records show the Conception passed its two most recent inspections with no safety violations. 2408

LOS ANGELES (AP) — Kevin Hart has a new job — he will host the 2019 Academy Awards, a role the prolific actor-comedian says fulfills a longtime dream.Hart announced his selection for the 91st Oscars in an Instagram statement Tuesday. The Academy of Motion Picture Arts and Sciences followed up with a tweet that welcomed him "to the family."The announcement came hours after trade publication The Hollywood Reporter posted a story calling the Oscars host position "the least wanted job in Hollywood."Hart clearly doesn't feel that way, writing on Instagram that it has been on his list of dream jobs for years. The 2019 Oscars will be broadcast Feb. 24 on ABC."I am blown away simply because this has been a goal on my list for a long time...To be able to join the legendary list of host that have graced this stage is unbelievable," Hart wrote. "I know my mom is smiling from ear to ear right now."I will be sure to make sure this years Oscars are a special one," Hart wrote.Hart takes over hosting duties from Jimmy Kimmel, who presided over the last two ceremonies, including 2016's flub that resulted in the wrong best picture winner being announced. Last year's ceremony was an all-time ratings low, and the film academy has announced a series of changes to the upcoming show .Those include shortening the broadcast to three hours, and also presenting certain categories during commercial breaks and broadcasting excerpts of those winners' speeches later in the show.The 39-year-old Hart has become a bankable star with films such as "Ride Along," ''Jumanji: Welcome to the Jungle" and "Night School."Celebrities including Martin Lawrence and Chris Rock, who hosted the ceremony in 2005 and 2016, posted congratulatory messages about Hart's selection Tuesday night."Damn I've lost another job to Kevin Hart," Rock posted on Instagram, echoing a joke he told during his 2016 opening monologue . "They got the best person for the job." 1946
